Abstract (en)
[origin: US5811210A] PCT No. PCT/JP94/01642 Sec. 371 Date Sep. 11, 1995 Sec. 102(e) Date Sep. 11, 1995 PCT Filed Sep. 30, 1994 PCT Pub. No. WO95/10071 PCT Pub. Date Apr. 13, 1995The present invention relates to a water-less lithographic raw plate, in which a photosensitive layer and a silicone rubber layer are laminated in this order on a substrate, comprising: the peel bonding strength between the photosensitive layer and the silicone rubber layer being 5 to 100 g/cm, and the initial elastic modulus of the photosensitive layer after completion of exposure being 5 to 75 kgf/mm2. In the present invention, attention is paid to the peel bonding strength between the photosensitive layer and the silicone rubber layer before exposure, and it is intensified, while the photosensitive layer after completion of exposure is kept lower in elastic modulus, to provide a water-less lithographic printing plate excellent in printing durability and image reproducibility. Therefore, the water-less lithographic printing plate obtained is suitable for commercial web offset printing and newspaper web offset printing.
